The articles in this volume of Documenta Missionalia are for that reader who is not just a curious learner of Tantrism and Christianity but who is also willing to allow the interaction of two religious worldviews to finally arrive at a unique realization and admiration of the ineffable mystery of God. Any reader interested in this theme would find in these articles great intellectual and spiritual depth that could eventually be highly profitable for one's academic and personal life. The authors of the articles in this volume, bearing in mind the perennial necessity of interreligious dialogue for mutual enrichment, have sought a comparative presentation of Tantric and Christian beliefs and practices like the Eucharist, divinization, mystical non-dualistic consciousness, male-female unity, Logos-Vac (Word) "inter-reading", freedom, fullness of joy, and corporeality. To our knowledge, such a diverse thematic presentation of Tantrism and Christianity in one single volume is the first of its kind to date.
